General Data



Overview

The SIRIUS 3RW30 soft starters reduce the motor voltage through variable phase control and increase it in ramp-like mode from a selectable starting voltage up to mains voltage. During starting, these devices limit the torque as well as the current and prevent the shocks which arise during direct starts or wye-delta starts. In this way, mechanical loads and mains voltage dips can be reliably reduced.

Soft starting reduces the stress on the connected equipment and results in lower wear and therefore longer periods of trouble-free production. The selectable start value means that the soft starters can be adjusted individually to the requirements of the application in question and unlike wye-delta starters are not restricted to two-stage starting with fixed voltage ratios.1)

The SIRIUS 3RW30 soft starters are characterized above all by their small space requirements. Integrated bypass contacts mean that minimal power loss is used at the power semiconduc-tors (thyristors) after the motor has started up. This cuts down on heat losses, enabling a more compact design and making exter-nal bypass circuits superfluous.

Various versions of the SIRIUS 3RW30 soft starters are available:• Standard version for fixed-speed three-phase motors, sizes

S00, S0, S2 and S3, with integrated bypass contact system• Version for fixed-speed three-phase motors in a 22.5 mm

enclosure without bypass

Soft starters rated up to 75 Hp (at 460 V) for standard applica-tions in three-phase networks are available. Extremely small sizes, low power losses and simple start-up are just three of the many advantages of this soft starter.

1) Actual motor start times are load dependent.

Application

The 3RW30 soft starters are suitable for soft starting of three-phase asynchronous motors.

Due to two-phase control, the current is kept at minimum values in all three phases throughout the entire starting time. Due to continuous voltage influencing, current and torque peaks, which are unavoidable in the case of wye-delta starters, for instance, do not occur.

Application areas • Pumps• Heat pumps• Hydraulic pumps• Presses• Conveyors• Roller conveyor• Screw conveyors

More information

Application examples for normal starting (Class 10)

Note:These tables present sample set values and device sizes. They are intended only for the purposes of information and are not binding. The set values depend on the application in question and must be optimized during start-up. Actual start times are load dependent.The soft starter dimensions should be checked where necessary with the Win-Soft Starter software or with the help of Technical Assistance.

Configuration

The 3RW solid-state motor controllers are designed for easy starting conditions. In the event of deviating conditions or in-creased switching frequency, it may be necessary to choose a larger device. For accurate dimensioning, use the Win-Soft Starter selection and simulation program.

If necessary, an overload relay for heavy starting must be se-lected where long starting times are involved. PTC sensors are recommended.

In the motor feeder between the SIRIUS 3RW soft starter and the motor, no capacitive elements are permitted (e. g. no reactive-power compensation equipment). In addition, neither static sys-tems for reactive-power compensation nor dynamic PFC (Power Factor Correction) must be operated in parallel during starting and ramp-down of the soft starter. This is important to prevent faults arising on the compensation equipment and/or the soft starter.

All elements of the main circuit (such as fuses, controls and over-load relays) should be dimensioned for direct starting, following the local short-circuit conditions. Fuses, controls and overload relays must be ordered separately. Please observe the maxi-mum switching frequencies specified in the technical specifications.

Note:When induction motors are switched on, voltage drops normally appear on starters of all types (direct starters, wye-delta starters, soft starters). The infeed transformer must always be dimen-sioned such that the voltage dip when starting the motor remains within the permissible tolerance. If the infeed transformer is di-mensioned with only a small margin, it is best for the control volt-age to be supplied from a separate circuit (independently of the main voltage) in order to avoid the potential switching off of the soft starter.

Power electronics schematic circuit diagram

A bypass contact system is already integrated in the 3RW30 soft starter and therefore does not have to be ordered separately.

Overview

SIRIUS 3RW40 soft starters have all the same advantages as the 3RW30 soft starters. The SIRIUS 3RW40 soft starters are characterized above all by their small space requirements. Integrated bypass contacts mean that minimal power is used at the power semiconductors (thyristors) after the motor has started up. This cuts down on heat losses, enabling a more compact design and making exter-nal bypass circuits superfluous. At the same time this soft starter comes with additional inte-grated functions such as adjustable current limiting, motor over-load and intrinsic device protection, and optional thermistor mo-tor protection on some models. Internal intrinsic device protection prevents the thermal over-loading of the thyristors and the power section defects this can cause. As an option the thyristors can also be protected by semiconductor fuses from short-circuiting. Thanks to integrated status monitoring and fault monitoring, this compact soft starter offers many different diagnostics options. Up to four LEDs and relay outputs permit differentiated monitor-ing and diagnostics of the operating mechanism by indicating the operating state as well as for example mains or phase failure, missing load, non-permissible tripping time/class setting, ther-mal overloading or device faults.Soft starters rated up to 300 Hp (at 460 V) for standard applica-tions in three-phase systems are available. Extremely small sizes, low power losses and simple start-up are just three of the many advantages of the SIRIUS 3RW40 soft starters.

"Increased safety" type of protection EEx e according to ATEX directive 94/9/EC

The 3RW40 soft starter sizes S0 to S12 are suitable for the start-ing of explosion-proof motors with "increased safety" type of pro-tection EEx e. See "Appendix" –> "Standards and approvals" –> "Type over-view of approved devices for potentially explosive areas (ATEX explosion protection)".

Application

The SIRIUS 3RW40 solid-state soft starters are suitable for soft starting and stopping of three-phase asynchronous motors.Due to two-phase control, the current is kept at minimum values in all three phases throughout the entire starting time and dis-turbing direct current components are eliminated in addition. This not only enables the two-phase starting of motors up to 300 Hp (at 460 V) but also avoids the current and torque peaks which occur e. g. with wye-delta starters.

Note:These tables present sample set values and device sizes. They are intended only for the purposes of information and are not binding. The set values depend on the application in question and must be optimized during start-up. Actual start times are load dependent.

The soft starter dimensions should be checked where necessary with the Win-Soft Starter software or with the help of Technical Assistance.

Configuration

The 3RW solid-state soft starters are designed for easy starting conditions. In the event of severe conditions or increased switching frequency, it may be necessary to choose a larger de-vice. For accurate dimensioning, use the Win-Soft Starter selec-tion and simulation program.Where long starting times are involved, the integrated solid-state overload relay for heavy starting should not be disconnected. PTC sensors are recommended. This also applies for the smooth ramp-down because during the ramp-down time an additional current loading applies in contrast to free ramp-down. In the case of high switching frequencies in S4 mode, Siemens recommends the use of PTC sensors. For corresponding device versions with integrated thermistor motor protection or separate thermistor evaluation devices see Industrial Controls catalog Chapter 11 “Function Relays, Interfaces and Converters“.In the motor feeder between the SIRIUS 3RW soft starter and the motor, no capacitive elements are permitted (e. g. no reactive-power compensation equipment, PFC capacitors). In addition, neither static systems for reactive-power compensation nor dy-namic PFC (Power Factor Correction) must be operated in par-allel during starting and ramp-down of the soft starter. This is im-portant to prevent faults arising on the compensation equipment and/or the soft starter.All elements of the main circuit (such as fuses and controls) should be dimensioned for direct starting, following the local short-circuit conditions. Fuses, controls and overload relays must be ordered separately. Please observe the maximum switching frequencies specified in the technical specifications.

For Operation in the Control Cabinet3RW Soft Starters3RW44 for high-feature applications

Overview

In addition to soft starting and soft ramp-down, the solid-state SIRIUS 3RW44 soft starters provide numerous functions for higher-level requirements. They cover a performance range up to 900 Hp (at 460 V) in the inline circuit and up to 1600Hp (at 460 V) in the inside-delta circuit.

The SIRIUS 3RW44 soft starters are characterized by a compact design for space-saving and clearly arranged control cabinet layouts. For optimized motor starting and stopping the innova-tive SIRIUS 3RW44 soft starters are an attractive alternative with considerable savings potential compared to applications with a frequency converter. The new torque control and adjustable cur-rent limiting enable the High-Feature soft starters to be used in nearly every conceivable task. They guarantee the reliable avoidance of sudden torque applications and current peaks dur-ing motor starting and stopping. This creates savings potential when calculating the size of the switchgear and when servicing the machinery installed. Whether it’s for inline circuits or inside-delta circuits – the SIRIUS 3RW44 soft starter offers savings es-pecially in terms of size and equipment costs.

The bypass contacts already integrated in the soft starter by-pass the thyristors after a motor ramp-up is detected. This re-sults in a further reduction in the heat loss occuring during oper-ation of the soft starter.

Combinations of various starting, operating and ramp-down possibilities ensure an optimum adaptation to the application-specific requirements. Operation and commissioning can be performed with the menu-controlled keypad and a menu-prompted, multi-line graphical display with background lighting. The optimized motor ramp-up and ramp-down can be effected quickly, easily and reliably by means of just a few settings with a previously selected language. Four-key operation and plain-text displays for each menu point guarantee full clarity at every mo-ment of the parameterization and operation.

Applicable standards• IEC 60947-4-2• UL/CSA

Application

In addition to device-specific parameterization, the programs of the SIRIUS ES software family also provide the following func-tionality in a uniform look and feel. These functions are available in many SIRIUS ES programs.

• Standards-conform printoutsThe programs of the SIRIUS ES software family greatly simplify machine documentation. Parameterization printouts accord-ing to EN ISO 7200 are possible. The elements to be printed are easy to select and compile as required.

• Easy creation of parameter templatesParameter templates can be created for devices and applica-tions with only minimum differences in their parameters. These templates contain all the parameters which are needed for the parameterization. In addition it is possible to specify which of these parameters are fixed and which can be customized, e. g. by the startup engineer.

• Group functionFor the user-friendly parameterization of numerous devices or applications of the same type, the programs of the SIRIUS ES software family offer a group function which enables the pa-rameterization of several devices to be read out or written through PROFIBUS. In conjunction with templates it is even possible to selectively adapt the same parameters in any number of parameterizations.

• Teleservice through MPIThe premium versions of the SIRIUS ES software families sup-port the use of MPI Teleservice (comprising the Teleservice software and various Teleservice adapters) for remote diag-nostics of the devices. This facilitates diagnostics and mainte-nance and it shortens response times for service purposes.

The Soft Starter ES software permits the quick and easy param-eterization, monitoring and diagnostics of SIRIUS 3RW44 High Feature soft starters for service purposes. The device parame-ters can be configured directly on the PC and transferred to the soft starter through a serial cable or an optional PROFIBUS inter-face.

The advantages of Soft Starter ES:• Clearly arranged configuring of device functions and their pa-

rameters – online and offline• Effective diagnostics functions on the soft starter and display

of the most important measured values• Trace function (oscilloscope function) for recording measured

values and events (in the Soft Starter ES Standard and Pre-mium software versions).

Circuit concept

The SIRIUS 3RW44 soft starters can be operated in two different types of circuit.• Inline circuit

The controls for isolating and protecting the motor are simply connected in series with the soft starter. The motor is con-nected to the soft starter with three cables.

• Inside-delta circuit The wiring is similar to that of wye-delta starters. The phases of the soft starter are connected in series with the individual motor windings. The soft starter then only has to carry the phase cur-rent, amounting to about 58 % of the rated motor current (con-ductor current).

Comparison of the types of circuit

Inline circuit:Rated current Ie corresponds to the rated motor current In,3 cables to the motor

Inside-delta circuit:Rated current Ie corresponds to approx. 58 % of the rated motor current In, 6 cables to the motor (as with wye-delta starters)

Which circuit?

Using the inline circuit involves the lowest wiring outlay. If the soft starter to motor connections are long, this circuit is preferable. With the inside-delta circuit there is double the wiring complexity but a smaller size of device can be used at the same rating. It is also recommended to use an isolating contactor in series with each motor winding.

Thanks to the choice of operating mode between the inline cir-cuit and inside-delta circuit, it is always possible to select the most favorable solution.

The braking function is possible only in the inline circuit.

Configuration

The 3RW44 solid-state soft starters are designed for normal starting. In case of heavy starting or increased starting fre-quency, a larger device must be selected.

For long starting times it is recommended to have a PTC sensor in the motor. This also applies for the ramp-down modes smooth ramp-down, pump ramp-down and DC braking, because during the ramp-down time in these modes, an additional current load-ing applies in contrast to free ramp-down.

In the motor feeder between the SIRIUS 3RW soft starter and the motor, no capacitive elements are permitted (e. g. no reactive-power compensation equipment). In addition, neither static sys-tems for reactive-power compensation nor dynamic PFC (Power Factor Correction) must be operated in parallel during starting and ramp-down of the soft starter. This is important to prevent faults arising on the compensation equipment and/or the soft starter.

All elements of the main circuit (such as fuses and controls) should be dimensioned for direct starting, following the local short-circuit conditions. Fuses, controls and overload relays must be ordered separately.

A bypass contact system and solid-state overload relay are al-ready integrated in the 3RW44 soft starter and therefore do not have to be ordered separately.

The harmonic component load for starting currents must be taken into consideration for the selection of motor starter protec-tors (selection of release).


Device interface, PROFIBUS DP communication module, Soft Starter ES parameterizing and operating software

The 3RW44 electronic soft starters have a PC interface for com-municating with the Soft Starter ES software or for connecting the external display and operator module. If the optional PROFIBUS communication module is used, the 3RW44 soft starter can be integrated in the PROFIBUS network and commu-nicate using the GSD file or Soft Starter ES Premium software.
